by Rami al-Qadir » Jul 17, 2017 Hi all, First post, so sorry if it's been discussed, but I haven't seen it yet. I appreciate any help! I am shopping for a ring for my girlfriend to magically turn her into my fiance. Been doing a lot of research about grading, and came across an issue I can't figure out on my own. I understand that De Beers rings above 1 carat come with an IIDGR certficate and a GIA certificate, but so far the used ones I'm looking for online only come with a De Beers passport and not IIDGR. Is this the same thing? Are they graded in the same lab? Should I be suspicious? Also - stupid question, but what is the point of having both certificates? Don't they show the same thing? Thanks!
